I think my mom's gift to the kids may be a plasma car for DS and a mini kick scooter for DD. She doesn't mind not getting them on sale. Amazon seems to have a plasma car with polyurethane wheels. Is that a good idea? Would they be better/more durable/less likely to scratch the floors than the plastic wheels? The price difference is negligible. The kids (6 and almost 3) will use the car inside (on our wood floors) during the winter and outside in good weather.
